IMPROVEMENT m APPARATUS FOR THE MANUFACTURE OF VINEGAR.

Specification forming part of Letters Patent No. 110,229, dated December 20, 1870. i

To all gohom it may concern:

Be it known that I, THEODORE GRUND- MANN, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new .and Improved Vinegar Apparatus; and I do hereby declare that the following is a full,

7 clear, and exact description thereof, which will enable others skilled inthe art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in whie Figure 1 represents a vertical longitudinal section of my improved vinegar apparatus, a: a: being the section-line. Fig. 2 is a vertical transverse section of the same, 313/, Fig. 1,being the section-line.

Similar letters of reference indicate corresponding parts.

This invention relates to certain improve-I ments on the apparatus 'for making vinegar now in use, and has for its object, chiefly, to

' avoid the use of braided straw or other fabric,

and to permit the employment of plain loose straw, cane, branches of trees or shrubs, or other simple material.

. The invention consists in arranging within the outer case or chamber a frame eontainin g a series of cross-bars, on which the straw or other loose material is supported in a series of horizontal layers. v

' The invention consists, also, in the use of an adjustable self-dumping trough, whereby the liquor is introduced in the apparatus at cera tain desired intervals.

1A in the drawing represents the outer "chamber or case, in which the oxidizing process is to be carried on. It is made in secrtiOllS, so that it may be taken apart, or of other suitable construction. \Vithin it is set up an open frame, B, containing a series of horizonal longitudinal side bars, a a, which are 1 held-on uprights b, as shown.

The side bars, a, are notched at suitable distances apart to receive the ends of cross-bars c 0. Upon these cross-bars are placed layers, d, of straw, cane, twigs, or other loose mate- "rial, the several layers being at suitable distances apart. V v g The fermenting liquor 1s, through an opening, 0, in the cover of the case A, poured into a swinging distribu tin g box or trough, G, which is pivoted at the ends to cars projectingfrom the perfbrated top plate, f.

Arms y 9 project from one side of the trough, and serve to support a bar, 7:, from which a weight, i, is suspended.

The liquor flows into the trough through the opening 0, and is, when said trough is filled sufficiently heavy to dump the same, to be discharged upon theplatef.

When the trough is emptied it is again swung up by the weight i, to receive the req- I uisite amount of liquid before being again dumped, thus giving the former content-s time to be distributed through the machine.

The weighted bar can be moved 011 the; arms g, and thereby regulates the amount of liquor necessary for dumping the trough.

The liquor poured upon the perforated plat a f trickles down upon the upper layer, d, of straw, or equivalent material, and will gradually find its way from one layer to another until it is finally collected in a bottom recep-' taele, D, whence it can be drawn 013' at will.

\Vhile the liquor slowly passes from one layer to another, and while it is spread on the several pieces of straw or other material, it is in thin films exposed to the air which passes through the case A, and is fully oxidized by the same.

The air-openings in the lower part of the case may be of suitable kind and distributed in suitable manner.

By the use of myimproved apparatus much room is saved, and the expensive matting heretofore' required, or the cumbersome slat-work,

is dispensed with.

This apparatus, owing to the thln flat layers, can be made much lower than any heretofore in use, while its length and width may be of suitable size. It may therefore be built to conveniently fit a room of ordinary size and 3. The pivoted trough 0, provided with the adj usable weight 2', to be made self-dump ing, substantially as herein shown and de-.

scribed.
